Oliver v. United States
Citation and Court
466 U.S. 170 (1984) — Supreme Court of the United States
Facts
Narcotics agents, ignoring “No Trespassing” signs, walked past the defendant’s home and a locked gate to a secluded field where they discovered a marijuana crop. Oliver argued this was a search of a constitutionally protected area.
Issue
Whether the Fourth Amendment’s protection of “persons, houses, papers, and effects” extends to open fields.
Holding
Open fields do not fall within the Fourth Amendment’s protection; government intrusions on open fields, however remote or secluded, are not searches within the meaning of the Fourth Amendment.
Rule / Doctrine
The open fields doctrine, first articulated in Hester v. United States (1924), holds that the special protection of the Fourth Amendment does not apply beyond the curtilage of a home. Open fields, even if privately owned, fenced, and posted with “No Trespassing” signs, lack the intimate activities and privacy expectations that the Fourth Amendment is designed to protect.
Significance
Reaffirmed and extended the open fields doctrine in the Katz era, holding that no legitimate expectation of privacy exists in open fields regardless of efforts to exclude others. The doctrine’s boundary with curtilage analysis was further developed in U.S. v. Dunn (1987).
